Get the local network IPv4 address of the current computer based on the default gateway.
All of the other Node.js modules I found picked the address of the first or a random external interface from os.networkInterfaces() or performed a DNS lookup on the hostname. What if I have VMware virtual interfaces, an OpenVPN connection, wifi, an ethernet cable, and some loopback interfaces with convincing-looking hosts entries all connected?
Under the hood, it just executes route.exe or netstat and parses the output with regular expressions.
``bash`
$ npm install --save local-ipv4-address
`javascript
var localIpV4Address = require("local-ipv4-address");
localIpV4Address().then(function(ipAddress){
console.log("My IP address is " + ipAddress);
// My IP address is 10.4.4.137
});
`
`bash``
$ node node_modules/local-ipv4-address
10.4.4.137
